hi,
I am very new to this topic. I am installed QWT from Ubuntu software centre. In .ui file I drag n drop the QwtPlot widget and I selected the slot as
void qwt::on_qwtPlot_legendChecked(QwtPlotItem *plotItem, bool on)
then I run the code, It giving an error QwtPlotItem is not declared. then I am try to include “#include <qwt_plot.h>” but it is also giving same error. What is my problem I am not getting anything.
If I want to include src n lib file of qwt-6.1.0 in qwt.pro file but I am not having this files because I am Installed directly from Ubuntu software centre. Where can I have this folders ?
please reply me It’s urgent
Can any one guide me
